| avian infectious encephalomyelitis | <veterinary> A disease of very young chicks caused by a picornavirus and characterised by tremor, ataxia, somnolence, and finally death. Synonym: epidemic tremor. (05 Mar 2000) |
| avian influenza | Infection of domestic and wild fowl and other birds with influenza a virus, avian. (12 Dec 1998) |
| avian leukaemia-sarcoma complex | A term applied to a group of transmissible virus-induced diseases of chickens causing sarcoma, myeloblastosis, erythroblastosis, leukosis, osteopetrosis, and lymphomatosis. These agents are closely related viruses (avian leukosis-sarcoma virus) causing prolferation of immature erythroid, myeloid, or lymphoid cells, a division of the RNA tumour viruses (subfamily Oncovirinae) causing the avian leukosis-sarcoma complex of diseases; the viruses are subgrouped according to antigenic characteristics and growth in defined types of tissue culture cells. Synonym: avian erythroblastosis virus, avian leukosis-sarcoma virus, avian lymphomatosis virus, avian myeloblastosis virus, avian sarcoma virus, fowl erythroblastosis virus, fowl lymphomatosis virus, fowl myeloblastosis virus. (05 Mar 2000) |
| avian leukosis | A group of transmissible, virus-induced diseases of chickens, characterised by proliferation of immature erythroid, myeloid, or lymphoid cells. It includes both leukaemic and solid-tumour forms. (12 Dec 1998) |
| avian malaria | <veterinary> Plasmodial infections of domestic and wild birds, transmitted chiefly by culicine mosquitoes. (05 Mar 2000) |
| avian monocytosis | An acute or subacute disease of young laying chickens characterised by lowered egg production, diarrhoea, frequently cyanosis of the head, and pathologic changes involving chiefly the liver and kidney; aetiology is not definitely established. Synonym: avian monocytosis. (05 Mar 2000) |
| avian myeloblastosis | Disease caused by the avian leukosis-sarcoma virus, which belongs to the family Retroviridae, characterised by progressive anaemia, enormous numbers of myeloblasts in the blood, weakness, and death. (05 Mar 2000) |
| avian reticuloendotheliosis | A leukosis-like disease of fowl caused by viruses of the avian type C retroviruses. (05 Mar 2000) |
| avian sarcoma | <tumour> A fibrosarcoma, originally observed in a Plymouth Rock hen, now thought to be an expression of infection by certain viruses of the avian leukosis-sarcoma complex in the family Retroviridae. Synonym: avian sarcoma, Rous tumour. (05 Mar 2000) |
| avian trichomoniasis | Trichomoniasis occurring in the upper digestive tract in a variety of birds and caused by Trichomonas gallinae; it causes necrotic ulceration in the mouth, oesophagus, crop, and proventriculus, frequently with rapid weight loss and death. (05 Mar 2000) |
| malaria, avian | Any of a group of infections of fowl caused by protozoa of the genera plasmodium, leucocytozoon, and haemoproteus. The life cycles of these parasites and the disease produced bears strong resemblance to those observed in human malaria. (12 Dec 1998) |
| paramyxoviruses, avian | A group of viruses in the genus rubulavirus causing disease in domestic fowl. There are many species, the most well-known being avian paramyxovirus 1 (newcastle disease virus). (12 Dec 1998) |
| retroviruses type c, avian | A genus of the family retroviridae with type c morphology, that causes malignant and other diseases in wild birds and domestic fowl. (12 Dec 1998) |
| sarcoma, avian | Connective tissue tumours, affecting primarily fowl, that are usually caused by avian sarcoma viruses. (12 Dec 1998) |
